结合该区烃源岩热演化、油气成藏时间、断裂活动史等成藏要素的四维耦合性剖析，结论认为：喜山期断裂泄压作用以及大量他源干气的侵入诱发了该区蒸发分馏作用的产生。

States Gaede s invention patent and the evolution history from the early mercury diffusion pump to oil fractionating diffusion pump .

本文叙述了盖得的发明专利，从初期的汞扩散泵到分馏油扩散泵的演变过程。

In reality, each cycle at a given temperature does not occur at exactly the same position in the fractionating column; theoretical plate is thus a concept rather than an accurate description.

实际上，一定温度下的每一周期并不是在分馏柱内的同一位置进行的，因而，理论塔板只是一个概念而不是精准描述。

Based on the postulated 2D average molecular unit structures proposed by Zhao et al, 3D conformations for the end-cuts of Athabasca bitumen pitch in Canada were created using polymethylene bridges with different lengths by the Computer Aided Molecular Design method.

利用分子模拟技术对加拿大Athabasca油砂沥青超临界萃取分馏残渣组分的化学分子结构进行了研究，首先选用长度不同的桥链构建了其三维平均结构，然后采用分子力学和分子动力学方法得到能量最低也即最稳定的构象。

Results According to the information at home and abroad and the research and the study result of toxicologic experiments,hygienic standard was drawn.

石油沥青是石油原油分馏后剩余的副产品，随着石油产量的增加，沥青的产量也随之增加。

The application of sulfur isotope tracing involves the physical and chemical conditions, origin of ore-forming minerals, denudating degree of orebody, ore enriching position and genesis types of deposits. In the application, the geology of the hydrothermal deposit should be well understand to distinguish metallogenic epochs and judge the isotopic fractional equilibrium state, combined with the Ohmoto mode to study the factors possibly affecting hydrothermal fluid system.

在总结前人研究基础上，综述了硫同位素在热液成矿作用中成矿物理化学条件、成矿物质来源、矿体剥蚀程度、矿化富集部位、矿床成因类型等的示踪意义，认为硫同位素示踪应用须在了解热液矿床基础地质前提下，准确区分成矿期次，判别硫同位素分馏平衡状态，结合Ohmoto模式综合研究影响成矿热液体系的各种因素才可以赋予同位素准确的地质内涵。

The Nutracor is a calcium soap of long chain fatty acids made from freshly processed fatty acid distillates of palm and reacted with calcium sources.
